Nintendo kicks off 3DS download game sales in a big way next week with New Super Mario Bros. 2 and Demon Training. Both first party titles will be available simultaneously at retail and as full downloads via the 3DS e-Shop.

To commemorate the occasion, Nintendo will be holding a campaign. Buy the download version of either game, and you'll receive Donkey Kong Original Edition on the 3DS Virtual Console and double the Club Nintendo points, or 40 points per game. Buy both games, and you'll also get an addition 20 Club Nintendo points as a bonus.
